康复训练对骨科术后深静脉血栓的预防作用

目的探讨康复训练对于骨科术后下肢深静脉血栓(DVT)的预防作用。方法选择68例骨科手术患者,术后进行下肢的被动及主动活动,包括踝关节的屈伸活动,膝关节的屈伸活动及股四头肌的等长收缩活动,应用彩色多普勒超声测定康复功能训练前与训练后下肢血流速度的变化。结果该研究中的病例均无DVT发生。踝关节、膝关节的主动、被动运动均可增加股动、静脉的血流速度,包括峰速度及平均速度,运动前后比较差异有统计学意义(P0.05),而且主动运动增加血流速度的幅度要明显高于被动运动(P0.05)。结论正规康复功能训练可促进患肢静脉回流,避免血流滞缓,达到预防下肢DVT的目的,具有简单、安全、有效、无创伤等优点,不需特殊设备,不会给患者增加经济负担,因此在临床及护理工作中有极大的应用价值。

The preventative effects of rehabilitation training on deep venous thrombosis after orthopedic surgery

Objective To evaluate the preventative effects of rehabilitation training on deep venous thrombosis after orthopedic surgery .Methods 68 patients after orthopedic surgery underwent rehabilitation training ,including active and passive movements , and the peak and average blood flow velocities before and after rehabilitation training were measured by using color ultrasound Doppler imaging .Results None of the 68 patients developed DVT .The active and passive movements of ankle joint and knee joint both increased the blood flow velocities of femoral artery and vein ,including peak and average blood flow .The active movements have more effects on the blood flow velocities than the passive movements .Conclusion Normative rehabilitation can increase ve‐nous return and avoid the blood flow too slow to prevent DVT .This method is without anticoagulant ,simple ,safe ,effective ,nonin‐vasive and has a great value in clinic and nursing service .
